Master
Cylinder
A cylinder containing a moveable piston actuated by foot pressure
producing hydraulic pressure to push fluid through the lines and wheel
cylinders and force the brake linings or pads against the drum or
disc.
Motor
Principally a machine that converts electrical energy into mechanical
energy.

Muffler
A chamber attached to the exhaust pipe in which the exhaust gases
expand and cool. It is usually fitted with baffles or porous plates
that reduce or muffle the noise created by the exhaust.

MSRP
Manufacturers suggested retail price.
Manufacturer Discounts
In some leases, particularly subvented leases, the manufacturer
reduces the MSRP, which lowers the purchase price of the vehicle,
which the lease is based on. This is a form of capitalized cost
reduction.

Mileage
Allowance
Mileage Allowance Lease agreements usually establish the average miles
per year that the car may be driven during the lease. This is often
between 12,000 and 15,000 miles. The lease contract also establishes
the amount you'll have to pay for every mile driven over the
allowance. This mileage fee is usually 15 cents per mile. You can
often purchase additional miles at the start of the lease at a
discounted rate. If you're sure you're going to drive more than the
number of miles allowed, then your best option is to negotiate for a
higher allowance on the lease.

Money
Factor
The most common way to express the base interest rate of a lease is as
a money factor. If you multiply a money factor by 2400, the result
will be equivalent to the base interest rate. The money factor of most
leases is known by a dealer's sales staff. The money factor measures
the cost of money, just like an interest rate. However, money factors
are used almost exclusively in leases, whereas interest rates are used
everywhere else.

Monthly Payment
The amount that must be paid each month to satisfy the lease contract.
It is common for the monthly payment shown in lease advertisements to
exclude applicable taxes, which will add to the amount paid each
month.
